I have irregular heartbeats and a mitral valve problem. What can I do?

I am having irregular heartbeats badly. Back in 2012, I was told by one place the mitral valve was back flowing and another valve had an issue. I take pravastatin. Before that, I took gembrozil since 1999, but I have stopped taking that. There seems to be pressure in chest and pain. The other day, I took a calcium score test to see if I was at risk for coronary heart disease. My score number was 8 which was low risk. I was given atenolol by regular doctor which I am scared to take. I have no regular heart doctor and I just got insurance about 4 months ago. What can I do?

Irregular heart beat could be from many different causes. Leakage of mitral valve is an especially important cause of this. If not properly treated, it may result in future problems. Your best option would be to get evaluated by a cardiologist and get appropriate treatment.
